Finally got my propane fireplace out and have replaced it with a used accentra insert. My house is now at the comfort level acceptable to all of the estrogen that resides in it. Normally my thermometer that is centrally located in my house(2 rooms away from the insert) wouldn't get above 68 °F on a warm day, now I've seen 72 °F since the insert has been up and running! PICS: 1. Propane pig 2. Stone cut, Framed up, ZC in 3. Both holes on outside (quite handy to have the old hole to install exhaust piping) 4. Exhaust complete 5. Exhaust/Siding complete (it's just under 48", SHHH) 6. Finished product in action!
